Installation on Straight Run Piping

Tracers are to be run parallel and in direct contact with the
process pipe where possible. Tracer location on pipe is to be
where most accessible. If more than two tracers are used,
they should be equally spaced circumferentially around the
pipe as shown in Illustration G.

1. Install tube or pipe tracers in accordance with Illustration

A (see T-3 and T-99 installation). Pressure test tracing for
leaks with steam pressure equal to or greater than the nor-
mal operating pressure or preferably with suitable hydro-
static tests. Repair any leaks and retest until tracing system
is free of leaks.

2. Place SnapTrace over tracer as shown in Illustration F be-

low.

• Banding should be a minimum of 12 mm x 0.5 mm for

ST-1 and ST-2 systems.*

• Banding should be a minimum of 12 mm x 0.5 mm for

ST-3, ST-4, ST-5 and ST-6 systems.*

• Banding tool should exert a force of 4450 N or greater.*

* Banding, crimp seals and tools meeting the required specifications are available

from Thermon.

5. Insulate and weatherproof piping.

Note . . .
For ease of installation and serviceability, all tracers shall be installed parallel to and

against the heated pipe or equipment and shall be placed on the most accessible sur-

face location in regard to supports, ease of installation, connection and thermal insula-

tion. Multiple tracers shall be equally spaced around the circumference of the pipe.
